PURPOSE: A concrete surface processing unit having dust collection function is provided, which keeps thickness of the waterproof layer constant by peeling the surface of the concrete structure. CONSTITUTION: A concrete surface processing unit having dust collection function comprises a dust collecting tank(110), a handle(170), a polishing device(120), a fixing unit, a motor, and a wheel chamber(140). The dust collecting tank provisionally stores dust from the concrete surface(1). The polishing device has a concavo-convex region(122) in the outer circumference in order to be close to the concrete surface. The fixing unit is projected from the right and left of the polishing device. The fixing unit clinches the polishing device on the dust collecting tank. The motor rotates the polishing device. The wheel(130) is installed on the inner surface of the wheel chamber. |
